I'm attending the PCB next week and I had a question for anyone who has done one recently. On the second day what time are you usualy finished?

The reason I ask is because my TA Bn have unwittingly organized a farewell dinner that evening not realizing the dates clash. I was wondering if I could get away for a few hours to say goodbye? The dinner is in London but I have my own car so could probably make a round trip in four or five hours.

I've phoned the admin cell but haven't had any luck because the relevant person is absent.
